What The Old Guard Taught Me

This week, I reflected on one of my favorite movies, The Old Guard, starring Charlize Theron. It’s about a group of immortals who’ve spent centuries saving lives and trying to make the world better—even when they’re unsure whether their actions truly matter.

One of the film’s most powerful moments comes near the end. After feeling defeated and questioning the value of their efforts, a scientist presents a collection of documents and photos spanning 150 years that reveals the truth: their actions changed the course of history. One person Andy saved went on to give birth to someone who later cured polio. Another inspired a human rights movement. Yet another sparked major scientific breakthroughs. Andy didn’t know it at the time—but her choices left a lasting mark.

It’s a beautiful example of the butterfly effect—how one small gesture can create far-reaching waves of change. One moment, one decision, one quiet act of courage can alter lives in ways we may never fully understand.

I’ve witnessed this in my own life. There have been moments when someone told me, years later, that something I said or did in passing changed the direction of their life. I had no idea. But it reminded me that our words and actions carry real power—even when the results are invisible.

And for the mentors, the thought leaders, and the people who quietly show up to support others—your everyday interactions matter more than you know. A simple moment of genuine care can shift someone’s path. That spark might set off the butterfly effect that leads to curing a disease, ending a war, or creating a movement for peace. We just don’t know.

I believe we’re all part of something greater. Each decision we make is a common thread connecting us to others. Every act of love, support, or service adds another strand to an invisible safety net—one that helps keep us all safe.

So let this be a reminder: stay intentional. Make your interactions meaningful. Because a simple act of kindness, advice, or just showing up may be the spark that transforms the world tomorrow.
